How to compare move-in and move-out photos with AI for a deposit claim

Set up photos the AI can compare

A comparison is only as good as the photos. Take move-in photos before the tenant moves belongings in and take move-out photos after the unit is empty, from the same spots. For each room keep a wide shot from each corner, plus close-ups of floors, walls, appliances and fixtures. Name files by room and date, for example kitchen-north-wall-2025-03-01.jpg. Photo basics are in baseline photos for claims and deposits.

Ask for differences, not conclusions

"Here are move-in and move-out photos of the same kitchen. List only visible differences, one per line, with the location. Do not say whether anything is damage, normal wear or the tenant's fault. Do not estimate a cost. If a difference might be a lighting or angle change, say so."

That wording matters. If you ask whether something is damage, the model may answer with confidence it cannot have. Asking for visible differences gives you a checklist to walk through in person.

Example a made-up kitchen comparison lists a stain on the floor near the stove, a missing cabinet handle and a scuff on the door frame. You inspect each in person, decide the scuff is normal wear and the floor stain and missing handle need repair.

You decide what is damage

Many states do not allow deductions for ordinary wear and tear, and they differ on how they define it. Keep your reasoning simple and written: what was found, why it is beyond normal use for the length of the tenancy, and what the repair costs, backed by a receipt or quote. For help pricing and wording each item see the AI security deposit letter checklist.

• Item and location, with the move-in and move-out photo names.
• Your reason it is damage and not normal wear.
• The cost, with an invoice or quote.

Watch the state deadline

State clocks are short and strict. In Florida, for example, if a landlord intends to claim part of the deposit, the statute requires written notice of the claim and its reason within 30 days after the tenancy ends, sent by certified mail to the tenant's last known mailing address or by email as the statute allows. The tenant then has 15 days to object in writing. A landlord who misses the 30 days loses the right to claim against the deposit. If no claim is made, the deposit is due back within 15 days.

That is Florida. Your state may use 14, 21, 30 or 45 days, and may add penalties. Use the date from your state's statute, not from the assistant, and put it on your calendar the day the tenant leaves.

Photos and privacy

Photos of an empty unit are low risk. If a photo shows the tenant, mail, documents or family pictures, crop it before uploading. Keep the original set in your own records.

How DoorKeeping handles it

Your connected assistant can read the tenant ledger, the deposit held for that tenant and the property's documents from DoorKeeping, and a helper's finish report for a job can include before and after photos, notes and receipts. The comparison of move-in and move-out photos is something you do in your assistant chat with the files you provide. Rent stays in your own bank account, and anything involving money or a legal step waits for your approval. Deductions and the deposit statement are your decision, and DoorKeeping gives no legal advice about your state's deposit rules.

Questions

Can ChatGPT tell me if something is damage?

It can list visible differences. Whether a difference is damage or normal wear is your judgment, based on your state's rules and the length of the tenancy.

How soon must I send the deposit statement?

It depends on your state. Florida requires notice of a claim within 30 days after the tenancy ends, others use different numbers. Check your statute.

What if the photos are not from the same angle?

Tell the assistant, and expect false differences. Check each one in person before you rely on it.

Do I need receipts for deductions?

Many states expect proof of cost. Keep invoices or quotes for every item you charge.
